P2385EGR Sensor E Circuit

- How the car detects it
- P2385 is the general circuit code for a fifth EGR-related sensor, labelled E. The letter is assigned by each manufacturer, so the code only makes sense on engines with an extensive set of EGR sensors, such as diesels that pair high- and low-pressure loops with several pressure and temperature probes. No manufacturer documents P2385 publicly. The closest published logic is for sensor D: Ford's 2024–2025 petrol summary stores P2380 when its smart EGR pressure sensor reports an internal error, and GM's 2025 diesel tables use the D codes for the low-pressure EGR differential pressure sensor. CARB requires circuit checks on every input the EGR monitor depends on. P2386 and P2387 narrow the fault to high or low signal; with any of them stored, EGR diagnosis is suspended or EGR reduced.
- What you may notice
- MIL on
- EGR monitor not completing, readiness stays open
- Possibly higher NOx and slightly changed engine response under load
- Likely causes
- LikelyConnector of EGR sensor E unplugged, damaged or corroded
- PossibleOpen or shorted wire between sensor and engine control unit
- PossibleSensor electrically failed
- RareShared 5 V reference supply faulty
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
- Repair
- Medium · Often possible to do yourself.Typical cost: €0 – €350
